GM Genuine Parts Fuel Injection Throttle Body Seals are designed, engineered, and tested to rigorous standards, and are backed by General Motors. These seals help provide an air- and liquid-tight connection between throttle body components, and are GM-recommended replacements for your vehicle's original components. Replace this seal whenever you service the throttle body. GM Genuine Parts are the true OE parts installed during the production of or validated by General Motors for GM vehicles. Some GM Genuine Parts may have formerly appeared as ACDelco GM Original Equipment (OE).
